Complete Java Web Services

Description

Duration: 4 Days

Description

The Complete Java Web Services class teaches students how to build Web Services and Web Service clients using Java technologies. The class includes a high-speed introduction to XML namespaces, XML Schema, SOAP, and WSDL before exploring Web service client or server-side development in Java APIs and tools. Specifically, this class focuses on JAX-WS.

Learning Objectives

•  Understand how Web services relate to Service Oriented Architecture.
•  Become familiar with the pillar Web service specifications for XML, XML Schema, SOAP, WSDL and UDDI.
•  Pick up design patterns and best practices for Web service interface documents.
•  Experience the development of Java Web services using the JAX-WS API.
•  See how WSDL and Schema elements map to Java objects.
•  Recognize and understand the difference between RPC and Document styled services.
•  Learn how to make and test Web services that are highly interoperable.

Audience

This class intended for developers that are going to implement SOAP-based Web services or Web service clients in Java.  Attendees should already have a good grasp of Java and server side development.  Attendees should already have a basic understanding of XML. 

Prerequisites

Students should have a good understanding of the Java programming language and a basic understanding of XML.  Students that have attended the Complete Java have the necessary background for this course.
